Memory effects of information acquired prior to marijuana usage?

So I understand that while high their are clear short-term memory losses, but after extensively searching I have yet to find anything regarding the effects of marijuana on learning that has occured prior to usage. For example, if you study all day, and then smoke (granted you leave at least an hour for what you learned to process before you start), what is the effect of that marijuana on your brain's ability to retain and imprint the learned material, and specifically, how might it affect the long-term storage which occurs as you sleep. Any help in the right direction would be useful--I never used to smoke after studying because I imagined there might be some adverse affect, but I have tried on a series of occasions now and I haven't noticed any differences. And for those of you (I know there will be some) who are tempted to answer my question with an inane comment about how bad weed is, I attend a top university and have near perfect grades, with an active social life, so hah. =P

I think you are not asking a question . I think that you are stating that you are lost about the subject.I would go back to that top quality university and ask for my money back because you still need some composition courses. The answer to what i think you're trying to say is, I would just get high and find out what its like to be high. Then I would compare being very busy doing something and see what you forget when someone asks you a question.
Reply:I'm 65 and I can't think of anyone who didn't smoke more or less. Some like it, I never cared for it. But I can't remember or even imagine someone having any ill effects, aside from getting caught. Booze, speed, even heart attacks from gambling, are deadly, but I never heard anything go wrong from pot.
Reply:my friend was really high thursday (he smoked 2 joints and popped 6 or 7 pills!!!) and he skipped the last 2 classes and didnt even remember where he went while he was skipping until yesterday wen my friend told him that his older brother drove him down the road from school 2 a gas station and dropped him off and still doesnt remember wat happened even tho our friend told him!!!!!!!!!

Reply:If you are in a top university and have near perfect grades why are you playing this game with yourself....that is if you are even doing this at all...and an inane comment would be any comment(s) that would support such a practice in the first place...Stopping smoking now would be the best thing you could do for yourself and your future...Marijuana is a drug that has long standing effects...memory loss chief among them.
Reply:I wish my husband's memory that we ever got married would vanish . Trust me this man has seen his share of partying days and he does not forget a damn thing.. Keep up the good grades and don't get caught or it could cost you alot and maybe your career that you are working so hard for. Good Luck . I think you being paranoid is more of a symptom than memory loss
